Zero schematic error

the Zero schematic shows DGI_GPIO1/3.1C going to pin 8 of J102 BUT that is the only appearance of DGI_GPIO1/3.1C and its source is not defined.

Same true for SDA/3.1C of pin 9 of J101 Same true for SCL/3.1C of pin 10 of J101

They’re there. They just seem to have an “extra” “/3.1C” part in the “label.” (Which I don’t know where it comes from, or what it means…)

Hi, it indicates the sheet it come from so it is not a bug :)
